Photoacoustic/Ultrasound Imaging for Breast Nodule Diagnosis, Molecular Classification, and Neoadjuvant Chemotherapy Response Evaluation

Sponsor: Peking Union Medical College Hospital

Summary

Photoacoustic (PA) imaging (PAI) emergerd as a rapidly evolving biomedical imaging modality, which combines the merits of optical imaging and ultrasound (US) imaging, and has a capacity in morphological, functional and molecular imaging, showing potential in visualizing superficial organs. The goal of this clinical trial is to build a PAI standardized scoring system to identify benign and malignant tumors, and use PAI to further determine the molecular classification of malignant breast tumors, and monitor the efficacy of neoadjuvant chemotherapy (NAC) in breast cancer. The main questions it aims to answer are: 1. How to build a standardized PA/US scoring system in differential diagnosis of benign and malignant tumors? 2. Can PAI precisely determine the molecular classification of breast tumors? 3. Can PAI systems predict the efficacy of NAC in breast cancer? Participants will receive regular PA/US imaging examinations during four stages of NAC (before NAC, 2 Cycles, 4 Cycles and 6 Cycles). And the effectiveness of PA/US in predicting NAC for breast cancer at different time points will be evaluated.
